– In order to estimate the influence of standard measurement conditions on filter design, this paper discusses the impact of the absence of the line impedance stabilization network (LISN) on conducted emissions and consequently on the optimized volume of passive EMC filter in a single-leg inverter system fed by a DC source.
– addressing the problem of using the LISN in a more critical case (DC sources and DC grids) compared to state of art (AC grids)
-The enhanced two-probe HF impedance measurement method with a new setup allows accurate measuring in higher frequencies compared to state of art (until 50 MHz compared to 30 MHz from state of art)
– comparison of filter volume designed for each case and showing the increase in volume related to this problem.
